ABSTRACT:
An oceanic seaplow system comprising a plurality of vessels forming a mini fleet wherein a flexible hose is joined at one end to a suction turbine associated with a mothership and the other end is connected to a suction stud on a seaplow travelling on the ocean bottom. Assistant vessels raise and lower the flexible hose and the seaplow by cables. One of the assistant vessels supplies air to an injector in the flexible hose through a pressure hose at one or more points for second stage acceleration of the dredged material. First stage acceleration takes place inside the seaplow through an electrolysis pump. Electricity for electrolysis and for the steering system is supplied through electric cables from one of the assistant vessels. The seaplow converts the forward motion of the plow by surface contact into rotation of plow elements in order to dig up specimens for elevation by the electrolysis pump located within the seaplow. The material dredged is accelerated through the flexible hose by the air injectors into the suction tubine and to the mothership for processing.
